HARRISBURG, Pa. — House Speaker Paul Ryan called for an Ethics Committee investigation Saturday after the New York Times reported that U.S. Rep. Patrick Meehan used taxpayer money to settle a complaint that stemmed from his hostility toward a former aide who rejected his romantic overtures. The story, published online Saturday, cited unnamed people who said the Republican Pennsylvania representative used thousands of dollars from his congressional office fund to settle the sexual harassment complaint the ex-aide filed last summer to the congressional Office of Compliance. In a statement, Ryan’s spokeswoman said the allegations must be investigated “fully and immediately” by the House Ethics Committee and that Meehan would immediately submit himself to the committee’s review.
